GDBus.Error:net.connman.Error.InvalidArguments

zmoshansky commented 8 years ago

Running sink/sink-test fails with GDBus.Error:net.connman.Error.InvalidArguments. Could you advise how one might begin to debug this issue?

System

Fedora 23 Wireless: Atheros AR9485 (ath9k) wpa_supplicant-2.4-7.fc23 connman-1.29-2.fc23

Pre-Run

$ sudo service NetworkManager stop
$ sudo service wpa_supplicant stop
$ sudo wpa_supplicant -ddt -u
$ sudo connmand -n -d

Activating WIFI, P2P, Scanning & Listing Peers in connmanctl all worked fine.

Standard Fedora wpa_supplicant rpm is compiled without CONFIG_WIFI_DISPLAY=y. Try rebuild wpa_supplicant with CONFIG_WIFI_DISPLAY enabled.

If that turns out to be the problem (and it seems likely), please file a bug with connman as well: the error message implies WDS gave invalid arguments to connman but that's not true, it's probably just an error message coming from supplicant telling connman that connman used invalid arguments.

I had this gdbus error mesage using Fedora stock wpa_supplicant rpm. After recompiling rpm with CONFIG_WIFI_DISPLAY enabled error has gone.

Still an issue on Fedora 25.

@mszakm was a bug filed with connman about this?
